Onshore, offshore or in-turbine electrolysis? Techno-economic overview of alternative integration designs for green hydrogen production into Offshore Wind Power Hubs

Massive investments in offshore wind power generate significant challenges on how this electricity will be integrated into the incumbent energy systems. In context, green hydrogen produced by emerges as a promising solution to remove barriers towards carbon-free economy Europe and beyond. Motivated recent developments Denmark with decision construct world's first artificial Offshore Energy Hub, paper investigates lowest cost for can achieved. A model proposing an design of electric infrastructure, determining levelised costs both electricity, is proposed. The economic feasibility production from Wind Power Hubs evaluated considering combination different electrolyser placements, technologies modes operations. results show that down 2.4 €/kg achieved offshore, competitive currently natural gas. Moreover, reduction up 13% registered when installed shaving peak loads.
